A good question and "Really" unanswerable At this time. I did think it was a might Bold (Cheeky) move to name the company that. TBH I would think that the port and rail plan will pretty much be as we all have seen being developed over the proceeding years.
For example "OPR" - Oakajee port and rail (or there equivalent) I think it may be "Infrastructure WA" will have a large share of the action, maybe 25% , then have a consortium of companies to fulfil the project.
I have no doubt in that scenario that the Shanghai investor through ANS will want as much of the project as possible seeing we have the Yilgarn IP --- All my thoughts of course.
I assume we would be on a very similar time frame as to what has once again already been mapped out
